Answer:
[tex]-4 + 3m + 4n[/tex]
Step-by-step explanation:
In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.
So we should start on the number without variables:
23 and 27
Match them up together and you should find your first equation:
23 - 7
==> -4
So we should have -4 + 8m + 4n - 5m
Now we should combine the numbers with the variable of m:
8m and 5m
Match them up together and you should find your first equation:
8m - 5m
==> 3m
So we should now have -4 + 3m + 4n
Since there are no other variables of n, we are all done:
-4 + 3m + 4n is your final answer
